Automatically hold Preorder orders (Alternative to REZ Shippings)

When to use this method?

Use this method when you:

• Want to use payment providers other than Shopify Payments
• Want to combine preorders with third-party apps (for example: subscriptions or bundles)

In these cases, you cannot use Shopify Selling Plans, which means REZ Discount, REZ Partial Payment, and REZ Shipping are not available.

We will create a flow like this
